Lung cancer patients with positive programmed death-ligand 1 expression endure graver postoperative pain.
Abstract
Postoperative pain after video-assisted thoracoscopic surgery (VATS) is common in lung cancer patients, and it is unclear whether cancer itself participates in pain regulation. Programmed cell death ligand-1 (PD-L1) expressed by tumors may be analgesic. Our study aimed to detect the association between PD-L1 and acute postoperative pain.
